Interested as I am in the problem of the formation of hydrogen gas
inside the primary cooling circuit in the pressurised water reactor
(PWR), I tried using www.google.com and looking at www.wikipedia.org,
but to no avail.

Can someone therefore please point me to W3 pages, PDFs, theses and the
like, on- or off-line, discussing the problem described above? If not,
can someone please point me to more appropriate NG(s) for this problem?
